His only son Pascal Najadi, who is AIAK deputy chairman and deputy chief executive, said he had full confidence in the police investigation.

"There has been good progress and I am confident that the Malaysian police will solve the case soon," he told the GDN from Russian capital Moscow.

"The Malaysian authorities are also amending their gun possession laws after my father's murder and it is a good sign that shows their seriousness."

Pascal, who has dual Swiss and British citizenship, said he was ready to assist Malaysian authorities in their investigation but cannot return to the country due to fears about his safety and security.

The 45-year-old revealed he was not aware of any property deals involving his late father as his company does not deal with it.

"We have nothing to do with any property deal. But I would like to say here that my father's wife (Kuen) has interests in property business," he said.

Hussain was previously convicted of embezzlement, but acquitted of all charges by Bahrain's Supreme Civil Appeals Court. His company founded the Arab Malaysian Banking Group (AMBG) in 1975, which is now a $16 billion banking group in Asia. – TradeArabia News Service
